As it should be. Tx. Documentation from ARM does not address commonalities very well I think.
In trying to do simple LED tests on eval kit boards in ASM I reviled the cut and paste documentation on the Control Registers for the GPIO where for each bit the doc simply states 'set this bit for this functionality', all the while my knowledge tells me many will do just that and brick their devices, because the other bits matter in every update/usage! |
